Having WHEA Errors Randomly But Seems To Start Happening Much More Frequent. It Was Fixed Back In March But Started Happening Again Recently. Already Changed GPU To No Avail. Although It Now Only Shows 1 WHEA Error.

Understanding and Troubleshooting WHEA Errors in Modern Systems

In today’s complex computing environments, hardware stability issues can manifest as sporadic errors that are sometimes difficult to diagnose. One such error, known as a WHEA (Windows Hardware Error Architecture) error, often indicates underlying problems with hardware components, such as the CPU, memory, or other critical system parts. This article explores common causes of WHEA errors, recounts a real-world user experience, and provides guidance on effective troubleshooting strategies.

Case Overview: Recurring WHEA Errors Post-Resolution

Recently, a user reported experiencing intermittent WHEA errors that seemed to become more frequent over time. Notably, these errors initially appeared back in March but were resolved after specific adjustments. However, in late July, the errors re-emerged, albeit with reduced frequency—typically occurring one to two weeks apart.

Key details include:
– The user’s Windows Event Viewer recorded two WHEA errors during incidents, but on subsequent occurrences, only one was present.
– Prior to the resurgence, the user had addressed stability issues by disabling Global C-States in the BIOS, which significantly reduced errors for about five months.
– Hardware changes included replacing the GPU with a Radeon RX 9070 XT, after which error frequency decreased temporarily.
– The user performed standard stability tests, such as Prime95, with no apparent issues.

These details suggest a complex interplay of potential hardware or firmware influences contributing to the errors.

Common Causes and Diagnostic Considerations

1. Hardware Stability and Overclocking:
   Although the user did not mention overclocking, stability issues can sometimes stem from overclocked components or inadequate power delivery. Running stress tests can help verify component stability.

2. Power Supply and Thermal Conditions:
   Fluctuations in power supply or thermal stress on high-performance components like the CPU or GPU can trigger hardware errors. Ensuring proper cooling and stable power delivery is crucial.

3. BIOS Settings and Firmware:
   Adjustments such as disabling C-States can impact system stability. Reviewing other BIOS settings, updating firmware, and resetting to default configurations can sometimes mitigate errors.

4. Hardware Components:
   The change to a different GPU resulting in fewer errors suggests graphics hardware might have been a contributing factor. However, persistent errors may also implicate other components like RAM, CPU, or motherboard.

5. Event Log Analysis and Additional Testing:
   Regularly monitoring Windows Event Viewer for
